**1. File Name Truncation:** * Windows and some other operating systems may truncate filenames to a certain length. This can lead to files with longer extensions having the extension cut off, leaving only the base filename and an apparent ".png" extension. **2. File Type Mislabeling:** * Some malware authors intentionally create files with misleading extensions to evade detection. They may use a ".png" extension for an executable file, falsely indicating it as a harmless image file. **3. Symbolic Links (Windows):** * Windows allows for the creation of symbolic links, which are essentially shortcuts pointing to a different file. An attacker could create a symbolic link with a ".png" extension pointing to an ".exe" file. **4. Alternate Data Streams (NTFS):** * NTFS filesystems support Alternate Data Streams (ADS), which are hidden data structures associated with files. An attacker could create an ADS with a ".png" extension and place the executable code within it. **5. Extended Attributes (macOS):** * macOS uses Extended Attributes to store metadata about files. An attacker could create an Extended Attribute with a ".png" extension and store the executable code within it. **6. File Renaming Utilities:** * There are legitimate file renaming utilities that allow users to change the extension of files. An attacker could use these utilities to rename an ".exe" file to ".png". **7. Windows Registry Edit:** * Advanced users can make changes to the Windows Registry to associate certain extensions with file types. An attacker could modify the registry to associate ".png" with the ".exe" file type. **8. File Repackaging Tools:** * There are tools that allow users to repackage executable files into different containers. An attacker could use these tools to create an archive file with a ".png" extension that contains the executable code. **9. Steganography:** * Steganography tools allow users to hide data within other files, such as images. An attacker could hide an executable file within a PNG image file, making it appear as a legitimate image. **10. Custom File Explorers:** * Some custom file explorers allow users to customize how files are displayed. An attacker could use such an explorer to display ".exe" files with a ".png" extension.

1. **Renaming the file:** - The file extension can be manually changed from .exe to .png using the file explorer or command line. 2. **Using a file extension spoofing tool:** - Tools like "ext2png" or "png2exe" can convert an .exe file into a .png file format that appears as a legitimate image but remains executable. 3. **Embedding an .exe file within a .png file:** - Advanced file management techniques can allow embedding an .exe executable within a .png image file. When the image is opened, the hidden .exe will be extracted and executed. 4. **Using a double file extension**: - In Windows, file extensions can be double-extended (e.g., .png.exe). This technique involves creating a .png file and then appending .exe to the end of the file name. However, this method may be detected by security tools. 5. **Exploiting short file name (SFN) limitation**: - The 8.3 file name convention in DOS and older versions of Windows limits file names to 8 characters followed by a 3-character extension. This can be used to disguise an .exe file as a .png file by naming it as "png.exe" with a space or underscore to shorten the name. 6. **Using a packed executable (PE) file:** - PE files, which are a type of executable format used in Windows, can be embedded within a .png file. This involves modifying the file structure to hide the executable code inside the .png's data. 7. **Exploiting file association bypass techniques**: - Security techniques exist to bypass normal file association checks. This allows .exe files with a .png extension to execute without triggering security warnings. However, this requires advanced technical expertise.
